TR Secondary circuit systems

Systems for the use of primary energy from -150 up to 400 °C

Secondary circuit systems use existing energy sources, such as steam, cooling water and brine – so-called primary systems. Here, the objective is to integrate the existing infrastructure and best possible use of the thermal energy on the primary side. In this way only a single heat transfer fluid circuit is used (single fluid system) on the consumer instead of steam, cooling water and brine circuits. Important advantages arise through the use of only one heat transfer liquid: due to the seamless and reproducible temperature
control throughout the whole temperature range changeover to different media is not required. Through the use of thermal oil low operating pressures prevail and the heat carrier also acts as a separating medium between the product and the environment.
